Explanation:
Detailed explanation-1: -The stronger the wind, the faster the spread of the fire. Wind brings an additional supply of air to the fire. It flattens the flame which pre-heats the fuel ahead and causes spot fires by blowing sparks and embers ahead of the main fire into new fuel sources.
Detailed explanation-2: -Cold weather can either aid or deter fire-starting, depending on several factors. For example, a cold front typically carries moisture and has wind. Wind increases the supply of oxygen to a fire and carries away combustion products. But, too much wind carries away the heat from an ignition source.
